New wheels; tire recomendations

[slimm]

i just got a new to me set of 21" style 128s. I hate the tires. way too noisy for my liking. i know the brand i want, but now i need size recommendations. they are currently wearing 245.35.21 and 285.30.21. i'm thinking of going with a meatier tire for a coupla reasons:

1: i think it would look better
2: slightly better ride

i also lowered her on eibach prokit springs. they haven't settled yet, as you can see in the pix. the sizes im referring to are 255.40.21 and 285.35.21. considering the drop, should i stick with the lower profile or go ahead and step up a little.any input would be greatly appreciated.
